Christian Horner says Red Bull wants to "rectify the situation" in this year's Canadian Grand Prix after Sebastian Vettel lost last year's race on the final lap.

Vettel had led almost the whole grand prix - which had featured a lengthy delay for torrential rain - when he came under late pressure from Jenson Button. On a drying track on the final lap, Vettel ran slightly wide off the dry line and allowed Button through to take victory. As a result Red Bull is yet to win in Canada, something that Horner told La Presse the team is eager to change.

"We love coming to Montreal," Horner said. "The city comes alive. It's always a great atmosphere. Even if the circuit is not the most exciting of the season, it has always produced exciting racing. This is one of the only races that Red Bull has never won, even though we came very close last year. It would be wonderful to come back and rectify the situation."

Red Bull became the first team to win two races in 2012 at the last grand prix in Monaco, but Horner said it was no guarantee that it will be able to challenge for victory this weekend.

"In Montreal, power is crucial. It's the complete opposite of Monaco. Who knows if we'll be competitive, but we'll be in attack mode.

"We are still young. This is our eighth car for our eighth season in formula one and we're still hungry. There is a great desire to do more. Our people enjoyed winning but we want more. Motivation at Red Bull has never been higher."

With Red Bull having to change its floor design in time for Canada following a potential protest from other teams, Horner admitted that being the championship leaders comes with its own problems.

"It doesn't get easier. Everything we do is scrutinised much more than if we were in the middle of the pack."
